Specification of Letters Patent.

Patented Oct. 8, 1907.

Application filed January 29, 1907. Serial No. 354,707.

To all whom'tt may concern:

Be it known that I, GUSTAV ANDERSON, a subject of the King of Sweden,residing at Dunlap, in the county of Morris, State of Kansas, haveinvented certain new and useful Improvements in Dehorners; and I dohereby declare the following to be a full, clear, and exact descriptionof. the invention, such as will enable others skilled in the art towhich it appertains to make and use the same.

This invention relates to dehorning tools and has for its primary objectto provide a tool of this class having a draw cut. It is a well-knownfact to those skilled in the use of such tools that in nearly every casethe horn is crushed to a greater or less degree due principally to thefact that the blade or blades of the tool move directly against the hornand not across it. The tool embodying my invention, however, includes ablade which is movable in both directions and with equal force in eachdirection.

Broadly speaking, the tool comprises a pair of spaced plates throughwhich are formed openings for the re-- ception of the horn, arms pivotedto the plate, a blade pivoted at one of its ends between the arms,handle le-- vers pivoted to the plates and connected one directly withthe blade and the other with the blade by means of aeonnecting bar. Inthis manner pressure of the handles toward each other will result in themovement of the blade longitudinally and against the horn.

In the accompanying drawings: Figure l is a view in elevation of adehorning tool constructed in accordance with my invention. one of theplates removed. Fig. 3 is a plan view of the tool. Fig. 4 is an end viewthereof, and, Fig. 5 is a similar view of the other end.

Referring more specifically to the drawings, the numeral 5 denotes apair of plates which are substantially triangular in form and which areprovided each with an opening 6, the openings in the said plates beingcoincident and being arranged for the reception of the horn to be cut.The plates are preferably secured together along the bottom or base ofthe triangle but above this portion are spaced from each other thethickness of a blade which is movable therebetween and which will bepresently described. -Pivoted upon opposite sides of the connectedportion of the plates is a pair of arms 7 which extend upwardly fromtheir pivot points and between the upper ends of the arms is pivotallyreceived the forward endof-a blade 8. This blade extends between theplates 5 and has its cutting edge 9 disposed in non-parallel relation toits back.

Fig. 2 is a similar view with.

0 The numeral 10 denotes a pair of triangular plates which are pivotedat their apex to the joined portion of the plates 5 upon opposite sidesthereof and secured to one end of the plate, which may be termed itslower end, is a handle 11.

The rear end of the blade 8 is received between the upper ends of theseplates 10 and pivoted to the plates 10 and the blade 8 by means of thebolt which pivotally connects the said blade and plates are the lowerends of connecting bars 12 and these bars are pivoted at their upperends to a handle lever 13 and upon opposite sides of the same. The lowerand forward end of the handle lever 13 is pivoted between the upper endsof the triangular plates 5 and above the blade 8.

From the foregoing it will be readily understood that by moving thehandle levers 11 and 13 toward each other, the blade will not only bemoved forwardly but it will also be moved downwardly and with equalforce in each direction and by reason of the fact that it movesforwardly and that the cutting edge of the blade is disposed at an anglea shearing action will be had upon a horn received through the openings6.

I have found it advisable to provide upon the blade a number of sharpcorrugations l4 resembling those in a file so that the blade may morereadily cut through the horn and I show these corrugations as extendingin parallel relation with respect to each other, at right angles to theknife edge of the blade, and from a point adjacent to the knife edge toapoin-t slightly removed therefrom.

What is claimed is:

An implement of the class described comprising a pair of angular plateshaving registering openings therein arranged for the reception of thehorn to be cut, :1 pair of arms pivoted to the plates, :1 blade pivotedat its forward end between the sp'aced upper ends of the said arms, saidblade being extended between the plates and having its cutting edgedisposed at an angle to its back, a pair of plates pivoted at the lowerrear corners of the first mentioned plates, the rear end of the bladebeing pivoted between the said plates at their upper ends, a handlesecured at one of its ends between the lower ends of the last mentionedplates, a handle pivoted at its forward end between the first mentionedplates and above the back of the blade, and links pivoted to the handleat their upper ends and to the rear end of the blade at their lower endssubstantially as described.

In testimony whereof, I atfix my signature, in presence of twowitnesses.

GUSTAV ANDERSON.
